요지즈미 카지 교수의 연구실은 대기 오염 물질인 오존과 일氧化탄소의 기상적·지리적 분포 및 기후 변화와의 상관관계를 연구합니다. 특히 위성 데이터와 지상 측정을 융합하여 북극권 주변의 숲 불씨와 대기 오염 배출 메커니즘을 분석하며, 오존 전구체 물질의 순환과 광화학 반응 메커니즘을 규명하는 데 초점을 맞추고 있습니다. 연구는 주로 시베리아 및 러시아 연해주 지역의 화재와 대기 오염 간의 상호작용을 중심으로 전개됩니다.

The NOAA 12 advanced very high resolution radiometer detected extensive forest fires in boreal Siberia and northern Mongolia during April through October 1998, a year of extremely dry weather, in particular, in the Russian Far East. Analysis of the satellite data has been carried out to estimate the area burned and gaseous emissions to the atmosphere from the point of view of ozone precursors. The fires started in western and eastern Siberia and moved eastward during the summer, until they were
Ground based measurements of ozone as well as carbon monoxide have been carried out at Happo station. Annual cycles of ozone and CO concentration were obtained. Monthly means of ozone show maximum of ca. 65 ppbv in April or May and minimum of ca. 45 ppbv in December or January. The annual behaviour of CO is somewhat similar to that of ozone showing maximum of 225 ppbv in April and minimum of 151 ppbv in December. A positive correlation was obtained between ozone and CO during spring and summer.
